Carrier 48XPN048090300 Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that will sense the precise flame during the initial ignition of the furnace. Because of the safety issues involved, when the sensor is triggered by an event the entire HVAC system will stop until the problem is remedied and the system is reset.
Subtle cues to watch for in a failing safety flame sensor
- The gas furnace will not begin working when you want it to
- HVAC system operates rarely when it wants to
- The main type of gas cannot begin an ignition sequence and closes the gas valve
